Description

WO 97/45266 WO 9745266PCTISG96 100005 1- Laminated--Sheet and Process for M~anufacture off a Laminated Sheet.
The Present invention relates to a laminated sheet and to a process for manufacturing the la-inated Sheet.
In particular the present invention relates to a laminated sheet comrnising sheets of metal foil and paper and a process for manufacturing the laminated sheet.
Laminated sheets, such as those made of sheets of metal foil and paper, can be used for a variety of functions including wrapping or packaging. consumer items, such as confectionery, are of ten wrapped individually or in bundles in laminated Sheets, and cigarettes and cigars are olten sold in tins or boxes having laminated sheets as a is liner. Laminated sheets are particularly useful as liners because the metal foil forms a barrier to light and moisture which could degrade the tobacco.
Laminated sheets are often printed or embossed with "images, such as trade marks, logos or company names of manufacturers or distributors, or other information in order to enhbance the presentation of goods wrapped or packaged in the laminated sheets.
in general, laminated sheets are printed or embossed on one side only. usually, the paper is printed or the metal foil is embossed, but occasionally both the metal foil is printed and the paper is embossed. The printing and embossing is -carried out by processes which are well known in printing technology, such as roll to roll embossing and intaglio printing.
While it is well known in the printing and. paper WO 97/45266 WO 9745266PCTSG96OOOO5 -2industry to produce a laminated sheet comprising ail embossed metal foil and printed paper, it has not hitherto been kcnow~n to provide a laminated sheet on which the printing and embossing are in registration, that is, on' which there in exact correspondence of the printed and embossed images.
An object of the present invention is to provide a laminated sheet comprising printed paper and embossed metal foil wherein the printing and embossing are in registration.
A further object of the present invention is to provide a process for misnfacturing such a laminated sheet.
According to the present invention there is provided a process for manufacturing a laminated sheet comprising the steps of: Mi adhering together a sheet of metal foil and a sheet of paper; (ii) printing an image on an outer surface of the paper, amd (i)embossing a mirror of the image on the metal foil in registration with the printed image on the paper.
According to the present invention there is provided a process for manufacturixig a laminated sheet comprising the steps of: Mi adherinlg together a sheet of metal foil and a sheet of paper; WO 97/45266 WO 9745266PCTSG96OOO -3- (ii) embossing an image on the metal foil; and (iii)printing a mirror of the image On the outer surface of the paper in registration with the embossed image on the metal foil.
As noted above, the order of the printing and embossing steps is not essential. However, it is preferred that the emfbossing step precede the printing step.
it is particularly preferred that the process comprises detecting the first formed of the printed and embossed images and cont rolling the aubsequent embosi ag/printing step to ensure registration of the subsequently formed printed and embossed images.
The step of adhering together the sheets of paper and metal foil may be carried out by any suitable method.
In a preferred embodiment, the metal foil is passed over a coating roller which applies adhesive to one surface of the metal foil. The paper and metal foil are then passed between a pair of rolls which press the paper and the adhesive coated surface of the metal foil togetherr to form tLhe laminated sheet.
The embossing step may be carried out by any suitable method. In one method of embossing, a worlcpiece (such as a roller) and embossing die is located on either side of the laminated sheet and brought together so that the die contacts and embosses the foil. In another method of embossing, the workpieae is stationery and the die is moved up and down against the metal foil of the laminated sheet. 3In another method of embossing, the workpiece is moved against the paper of the laminated sheet, thus WO 97/45266 WO 9745266PCT/SG96/00005 -4 pressing the metal foil against the embossing. die.
it is preferred that the embossing step comprises feeding the laminated sheet between the nip of two rolls, with one roll acting a a workpiece and being formed from a relatively soft material such as paper, and the other roll acting an a die and being formead from metal, such as steel.
The printing step may be carried out by any suitable method. For example, the printing step may comprise relief or letterpress printing, planographic printing or intaglio printing, such as photogravure or roll to roll gravure, The laminated sheet of the present invention may have physical characteristics appropriate for the intended -ae For example, where it is intended for wrapping the laminated sheet may need to be very flexible. Alternatively, where it is intended to line cigarette boxes, it may be necessary that the laminated aheet be relatively rigid so that it can be folded and maintain the folds.
Different physical charaoteristics of the laminated sheet- may be provided in part by choice of adhesive and the arade and type of paper and/or metal foil.
It is preferred that the metal foil comprise a metal chosen form the main group of the periodic table.
it is particularly preferred that the metal loll comprises or consists of aluminium.
optionally, the process of the present invention comprises colouring the metal foil. Preferably, the WO 97/45266 WO 9745266PCT/SG96/00005 colouring step comprises a roll to roll gravure printing process in which the whole surface of the metal foil is coloured by being passed across an inked gravure roll. The coloured ink deposited on the metal foil by the gravure roll may be dried by passing the metal foil through a hot air cha-ber or the like.
The present invention is described further by way of example with reference to the accompanying drawings in which: Figure I is a schematic diagram of a preferred embodiment of a process in accordance with the present invention for manufacturing a preferred embodiment of a laminated sheet in accordance with the present invention; Figure 2(a) is a plan view of the metal foil surface of the laminated sheet manufactured by the proces shown in Figure 1; Figure 2(b) is a plan view of the paper surface of the laminated sheet manufactured by the process shown in Figure 1; and Figure 3 is a cross section of the lami~mated sheet shown in Figures 2(a) and 2(b).
in the process shown in Figure 1 metal foil (3) and paper are fed. from respective reels and and are passed through a Series of workotations at which the metal foil and the paper are laminated together, an image is printed on the paper and a "mirror= image is embossed on the metal foil With reference to Figure 1, the metal foil typically silver aluminium foil, is passed from the reel WO 97/45266 PCT/SG96/00005 6 over a coating roll which deposits adhesive, preferably as an even film, over one surface of the metal foil The metal foil and paper from the reel are then passed between two laminating rolls (6a,6b) which press the adhesive coated surface of the metal foil evenly against one surface of the paper to form a laminated sheet.
The outer surface of the metal foil of the laminated sheet is then coloured by transporting the laminated sheet in contact with a gravure roll which deposits a layer of coloured ink on the outer surface of metal foil The wet ink is dried by passing the laminated sheet through a drying chamber in which hot air is circulated.
The laminated sheet is then passed across a gravure cylinder which leaves a printed image on the outer surface of the paper The wet ink on the paper is then dried by passing the laminated sheet through another drying chamber The laminated sheet is then passed to an embossing station which comprises a workpiece (12a) and a die (12b) which embosses on the metal foil a "mirror" image of the printed image on the paper A control assembly which includes a sensor (11) upstream of the embossing workstation detects the printed image on the paper and controls the process by any suitable means to ensure that the embossed "mirror" image on the metal foil is in registration with the printed image on the paper (4) Substitute Sheet (Rule 26) WO 97145266 PCT/SG96/00005 -7- Finally, the embossed and printed laminated sheet is fed onto a large reel (13) for storage prior to the sheet being cut and spooled onto smaller reels.
Figure 2 shows the outer surface of the metal foil of a section of the laminated sheet manufactured by the process described above on which is embossed an image (15) which comprises an array of the word "tobacco". Figure 2 shows the outer surface of the paper of the section of the laminated sheet shown in Figure 2 The outer surface of the paper is marked with a printed image (17) which comprises an array of the word "tobacco". The arrangement is such that there is correspondence in shape, size and position of the embossed and printed images.
Figure 3 is an enlargement of a cross section of part of the laminated sheet shown in Figures 2 (a) and 2 which shows the metal foil and the paper held together by a thin layer of adhesive (18).
The metal foil has impressions (19)where the embossing die has made contact and depressed the surface of the metal foil. As the embossing and printing are in registration, the paper has deposits of ink (20) which correspond to the impressions (19)in the metal foil (3) Figure 3 is an enlargement of a cross section of part of the laminated sheet shown in Figures 2 (a) and 2 which shows the metal foil and the paper held together by a thin layer of adhesive (18) The metal foil has impressions (14) where the embossing die has not made contact and depressed the surface of the metal foil. As the embossing and printing are in registration, the paper has deposits of ink (16) which correspond to the impressions (14) in the metal foil (3) WO 97/45266 PCUSG96/00005 8 It is noted that the particular image shown in Figures 2 and 2 is an arbitrary selection and that any suitable image may be embossed and printed on the laminated sheet.
It is also noted that the production of a laminated sheet having embossed and printed mirror images that are in registration is believed to be an important means of enabling purchasers of products, such as tobacco, to distinguish between the products of different traders.
In the tobacco industry, the principal benefit is in enabling detection of non-genuine cigarettes.
While the invention has been explained in relation to its preferred embodiments it is to be understood that various modifications thereof will become apparent to those skilled in the technology upon reading the specification.
